Torque converter stall

Call FTI in Deland, FL. They are up the road from me. I had a custom billet 4200 9 inch convertor made by them. It is very tight at part throttle and feels like a 2500 until I romp it, then hold on! Best $1100 I ever spent. Remember, ALL of your power passes through the converter. This makes it THE most important part of your drivetrain. Do not skimp here!
